How do I update my Harman Kardon firmware?
The firmware upgrade will be available at www.harmankardon.com at no charge to current owners. Consumers only need to download the software to a USB memory stick, insert the stick drive into the front panel USB jack on the AVR unit and use the remote to navigate through on-screen instructions to install the upgrade
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
